Can I edit a journal that's approved and not yet posted?

Yes. Here's how you do it.

From the Journals work area:

  1. Select the Manage Journals task.

  2. Search for the journal and open it.

  3. On the Edit Journal page, click Edit. A message will appear telling you that if you continue, the journal will return to an unapproved state. The approval status on the journal will change to Required.

  4. Click Save.

  5. Make your edits as needed.

  6. Resubmit the journal for approval.
